Re: [rules-users] How to access Guvnor Rules based on versions from Java?

2012-10-16 Thread Ravikiran 
Hi Jarvis,

Thanks for your reply. Looks like i have posted my intension unclearly. To
elaborate bit more, currently i am using Rest API to create KnowledgeBase
from my java client. I have changeset-loans.xml, where my guvnor package
with drl is defined. My java client will this to fire all rules of that
package. In such a case, when i have more one version created for the
package and the rule assets within it, how i can i call specific version
based package along with the drl file to fire all the rule assets belongs to
it? In the same passion, is there any way i can mentioned the rule asset
name in the changeset xml file to fire specific version of rule asset from
java?

I can only get the package or rule asset's metadata using the urls that you
have mentioned in your post. But i can't fire the rules...please suggest if
i am doing something wrong.

changeset-loans.xml
-
change-set xmlns='http://drools.org/drools-5.0/change-set'
xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
xs:schemaLocation='http://drools.org/drools-5.0/change-set

Re: [rules-users] 5.5 Beta1 Guvnor Issue 500 The call failed on the server

2012-10-15 Thread Ravikiran 
It may be not the corrent way of doing it.Let's do like this. If you are
using file based JCB for your repository, why can't you try copying the full
repository manually to your new location...It may work...but i am not sure.
It worked for me when i do it migrate the repository between two version of
guvnor.

[rules-users] How to access Guvnor Rules based on versions from Java?

2012-10-15 Thread Ravikiran 
Hi,
I have got a business requirement to access specific version of a rule and
process them accordingly. My rules are stored in file based JCB based guvnor
repository. For example, i have a rule in a package created, having more
than one version varying with rule definition for each version.
How do i access those version specific rules from my java client? Please
help.


thanks

Drools Guvnor v5.3  5.4 onwards uses weld and seam frameworks causing this
error. Though i do not have any clue about the given exception, But Guvnor
v5.2.0 works perfectly in Websphere AS7 without any issues. But remember, it
works only in Firefox browser. You'll end up ing seeing blank screen after
login to Guvnor in IE browser.

Hi All,

Drools Guvnor 5.2.0 Final successfully working on Websphere AS 7. As
described in my earlier posts, I was not getting blank screen displayed
after the new repository is created when i launch Guvnor for the first time.
I didn't have any clue about this behavior because it wasn't throwing any
exceptions too.

Root cause of this behaviour is browser version. It works successfully on
IE8, Firefox and Chrome. I was facing problem with IE6.Damm.

thanks...

I was almost there to start using guvnor with Websphere 7, but i am struck
now with the situation explained earlier. That to, no exceptions have been
thrown on server logs as well. Just blank screen with header part displayed

Appreciate any help or clue at this point of time...Also, please let me know

Hi,

Drools Guvnor 5.4.0 Final  - I came to know that this version may not work
successfully in Websphere because IBM Websphere uses OpenWebBeans as CDI
implementation. Where as JBoss uses weld and this seems to differ. Not very
sure about the implementation of two sides...is it?

Drools Guvnor 5.2.0 Final - This is deployed successfully deployed on
Websphere, and i got the blank page after the sample repository is created
during launching.

@Guvnor experts, do you suggest any other version of drools guvnor
distribution without weld that can resolve my above issues?

Thanks

[rules-users] Drools Guvnor 5.2 Issue on Websphere AS 7

2012-07-23 Thread Ravikiran 
Hi Drools gurus,

I am back again. As most of you know that i had many 'weld' related issues
for deploying Drools Guvnor 5.4 in Webspere 7. After all my trails, i have
decided to go for Guvnor 5.2 (which doesn't have weld+seam dependancies)
deployment on Websphere As7.
This time, I was able to deploy Guvnor 5.2.0 Final on Websphere AS7
successfully without any errors. I have changed the repository to my own
file path. When i launch the guvnor for the first it had asked me to load
the sample packages, i have chosen YES. It was succeffully loaded all sample
packages into my given file path. That's it, after the loading, my browser
window was completely blank except Drools logo on top left and
guest[signout] on top right.

Any Idea what was wrong with my setup. What should i do to get the guvnor
web...Please help. 

http://localhost:9080/drools-guvnor/org.drools.guvnor.Guvnor/Guvnor.html
I saw view source,

Is it something to do with 'org.drools.guvnor.Guvnor.nocache.js'?

Hi Geoffrey  Other Gurus

To throw more light on the above error message, please find below the
getCurrentUser() method snippet that i have taken from the source of
SecurityServiceServlet.java. Please tell me in what cases the
securityService comes as null for causing this exception.

public UserSecurityContext getCurrentUser() {
if (securityService == null) {
// This is the first method called by the client.
// If CDI hasn't kicked in (theoretically impossible...), throw
a readable exception
throw new IllegalStateException(CDI hasn't been properly

  Make sure your IDE classpath is in sync with the real

  The classpath should include weld-servlet.);

return securityService.getCurrentUser();

Hi Joffrey,

I have downloaded the distribution shows Drools-guvnor 5.3.0, but when i see
the Guvnor version from web UI (Adminstration--About) it shows the version
as SNAPSOT 5.4.0. Now i too suspect that my Guvnor is of version 5.4.0 only,
that's why all those errors were coming.

I feel that you have understood the problem now, please tell me what should
i do to resolve this. If i required to add any new jar files, please also
let me know the location to download them as well. Because i didn't get any
related information on internet for this issue so far...you are the only
hope!

Thanks a lot...

[rules-users] Drools Guvnor 5.4.0 - Rules integration with database (Oracle)

2012-07-16 Thread Ravikiran 
Hi,
I working on creating a POC by creating set of web based rules within a
package using drools Guvnor and accessing them from my Java client.
Currently, my drools uses Jackrabbit repository (2 foldersrepository and
scripts and 1 file repository.xml) which is created within bin folder of
my JBoss AS.
I have gone through the steps given in user guide for database integration,
I am using Oracle as my database and i generated oracle based repository.xml
using the administration in Drools Guvnor and placed it under my bin folder.
I have stopped the server and deleted exsting 2 folders and one xml file. I
have restarted my server with the deployment of drools-guvnor.war. When i
start the guvnor web, it has asked me whether to load the sample packages
for the fisrt time, i said yes.
Now when i go and see in bin directory, i could still see one respository
folder. Also, i could see there were 6-7 tables have been created in oracle
database which were belongs to jboss drools only.

I would need some experts suggestion here, 
is it the right way to do the rule integration with the database?
What is right way to promote the same changes to SIT or UAT?

Thanks in advance...

[rules-users] Drools Guvnor-Decison Tables - Rule is not being fired!!! Please help

2012-07-16 Thread Ravikiran 
Hi,
I'm using default Guvnor package mortgages decision table as example for
my POC. Below is the rules from the decision table. No rule is being fired
from my JAVA client out of 3 rules given below.

//from row number: 1
rule Row 3 Pricing loans
dialect mvel
when
 application : LoanApplication( amount  131000 , amount 
=
20 , lengthYears == 30 , deposit  2 )
income : IncomeSource( type == Asset )
then
application.setApproved( true );
application.setInsuranceCost( 0 );
application.setApprovedRate( 2 );
end

//from row number: 2
rule Row 1 Pricing loans
dialect mvel
when
application : LoanApplication( amount  1 , amount = 
10 ,
lengthYears == 20 , deposit  2000 )
income : IncomeSource( type == Job )
then
application.setApproved( true );
application.setInsuranceCost( 0 );
application.setApprovedRate( 4 );
end

//from row number: 3
rule Row 2 Pricing loans
dialect mvel
when
application : LoanApplication( amount  11 , amount = 
13 ,
lengthYears == 20 , deposit  3000 )
income : IncomeSource( type == Job )
then
application.setApproved( true );
application.setInsuranceCost( 10 );
application.setApprovedRate( 6 );
end

== My Java client follows
KnowledgeBase knowledgeBase = createKnowledgeBase(); //Successfully creates
knowledgebase
StatefulKnowledgeSession session =
knowledgeBase.newStatefulKnowledgeSession();

FactType appType = knowledgeBase.getFactType( mortgages,
LoanApplication );
FactType incomeType = knowledgeBase.getFactType( mortgages,
IncomeSource );

Object application = appType.newInstance();
Object income = incomeType.newInstance();

appType.set(application, amount, 10);
appType.set(application, deposit, 1500);
appType.set(application, lengthYears, 20);

incomeType.set(income, type, Job);
incomeType.set(income, amount, 65000);

session.insert(appType);
session.insert(incomeType);

assertTrue(session.getFactCount() == 2);
session.fireAllRules();
assertTrue(session.getFactCount() == 3);

Question: I hope the way i pass the input satisfies Row 2 Pricing loans
above. But My assertion is getting failed after calling
fireAllRules()...because the factcount was still 2. Please help what could
be the wrong in above scenario.

thanks a lot.

 The problem is that you are inserting the fact type definition instead of
 the facts themselves.

 instead of insert *appType* and *incomeType* you should insert *
 application* and *income*.

Re: [rules-users] Drools Guvnor-Decison Tables - Rule is not being fired!!! Please help

2012-07-16 Thread Ravikiran 
Thanks Esteban. It works fine after inserting the Fact instead of
FactType...!!!

But still i have one basic question in mind...if there are many rules
defined in my package, How would i know that which is rule has got fired
when i call fireAllRules() method whithout passing AgendaFilter. Also i know
that fireAllRules() gives me how many rules have got fired like int x =
session.fireAllRules()

I have defined specific set of rules defined in a package for one biz. logic
and deployed drools war seperately. From the Application integration
perspective, I should be able to know whether my rules is fired or not.
Based on the success or failure i'll have to do some biz. processing

Little confusing here...i know that i am almost there...but i need some
light here to understand better for the integration purpose.

Please help!!!

Thanks a lot in Advance...

2012-07-16 Thread Ravikiran 
Hi Drools gurus,

Further to my earlier post in the same thread, 

1) please clarify whether the respository folder still exists after the
database integration?
2) If the repository folder still exists even after database integration,
then there is something wrong with my process.
3) After the development is completed in my DEV. environment, How do i
promote my changes to SIT or different environment (means repository)?

Please let me know if you need more details...

thanks a lot.

Hi Davide,

I can write the listener to know what is happening underneath that will be
printed in a log, but when it comes to my biz. scenario i should have a
simple way that i can derive it from my java code. Because i have multiple
biz.flows based on certain biz.policies...those policies have to be derived
from the execution of specific rules within my package...

Can you please thorow little more light on this

thanks

[rules-users] How to Access Rule RHS (THEN Part) from JAVA?

2012-07-13 Thread Ravikiran 
Hi Drools Gurus,

One more newbie here for Drools Guvnor. I have chosen
guvnor-distribution-5.3.0.Final (I could see version as SNAPSHOT 5.4.0
within Guvnor--Administration--About) to start with. After reading through
the complete user manual, I was able to setup and deploy Drools Guvnor war
in JBoss AS 7.

My intension is to access all the rules that i have created using Guvnor
web. I have written a java test case to access my Rules which are resided in
a drools Package using REST API. I was successful to access them using
standard Authentication mechanism with charset*.xml. Even though i was able
to call fireAllRules with specific rule using AgendaFilter provided. But i
was not able to access the values at RHS after a specific rule got fired.
For Example, i want to access percent value as 2.5 after the below sample
rule is successfully executed,
I have uploaded my model jar to Guvnor containing Person  LoanFormula
classes.

---Rule 1 (please do not see the syntax errors)
WHEN
 Person age  25
 
THEN
 LoanFormula percent = 2.5
 
 

JAVA Code follows
-
KnowledgeBase kbase = ...
FactType personType = kbase.getFactType( org.drools.examples,Person );
Object bob = personType.newInstance();
personType.set( bob, name,Bob );
personType.set( bob,age,42 );
StatefulKnowledgeSession ksession = ...
ksession.insert( bob );
AgendaFilter filter = new ..(Rule1);
int count = ksession.fireAllRules(filter);
String name = personType.get( bob, name );
int age = personType.get( bob, age );

It would be great help if some one can show me the sample code for accessing
RHS part of the Rule. Please let me know if you need more details.

thanks
Kiru

[rules-users] Drools Guvnor - question on mortgages package in guvnor-distribution-5.4.0.Final

2012-07-13 Thread Ravikiran 
Hi,
I have deployed drools-guvnor.war version 5.4.0 in Jboss AS 7. When i launch
the guvnor for the first time, it also loads the defalult packages, one
package is called mortgages is also loaded. Mortgages package contans
totally 7 diff. rules, but when i go see the model of the mortgages i do not
see any classes displayed over there. But, i was able to build  create
deployment SNAPSHOT successfully. Even the rule DSL source contains all
classes like LoanApplication etc.,.

How is it possible? Do you mean, some kind of related drl file is uploaded
as a Model? please clarify?
